IMPROVEMENT IN LAMP-BURNERS.

To all about it may concern: I

Be it known that I, GEoRGE J. GAPEWELL, of West Cheshire, in thecountyof New Haven and State of Connecticut, have invented a new and usefulImprovement in Lamps; and I do hereby declare that the following is afull, clear, and exact description thereof, which will enable othersskilled in the art to make and use the same, reference being bad to theaccompanying drawings, forming a part of this specification.

The principal object of the present invention is to enable the wick of akerosene-lamp to be lighted without necessarily removing the chimney;and for this purpose it consists in incasing the wick within asuitable-shaped metallic casing, tube, or holder therefor, of therequisite length, which casing is arranged and slides looselyin theordinary wick-tube of the lamp, being operated by and through a pinionor spur wheel, interlocking with a toothed rack formed by indenting oneside of the said holder in the direction of its length, and either movedoutward or drawn into the ordinary wick-tube, carrying the wick with it,by turning'the said spur-wheel in the proper directions therefor, andthis invention still further consists in a novel manner of constructingor forming the ordinary draft-openings in the cap portion of the lamp,for the admission and supply of air to its flame, whereby theair-currents are caused to be deflected, as they enter the air-ghamberof the lamp, and thus prevented from acting upon the flame with suchforce or strength as to extinguish it, the importance of which isobvious to all.

In accompanying plate of drawings my in'r provements in lamps areillustrated, Figure 1 being a central vertical section through akerosene-lamp having my improvements applied thereto; Fig. 2, ahorizontal section, taken in the plane of the line 00 00, Fig. 1; Fig.3, a detail view of the wick-holder of the lamp.

Similar letters of reference indicate like parts.

A in the drawings represents the body portion of the lamp, having a top,B, applied to it, constructed in the ordinary manner practiced therefor,with the exception of the air-openings G to its air-chamber D, which aremade in such a manner that the air-currents, in pass ing through them,must enter between the side edges, a and b, of the same, as plainlyshown in Fig. 2, whereby they are deflected, as it were, in their courseto the flame, and thus prevented from acting upon it with so much forceor strength as to extinguish it, the our rents of air by this meansbeing, as is obvious, so retarded in their course that, before reachingthe flame, they 'must become heated to such an extent as to produce amore perfect combustion of the same.

F is the ordinary wick-tube of a kerosenelamp, but in the presentinvention made a little larger around its inside, in which is looselyplaced another tube or casin g, G, in ade of a similar shape thereto,having the wick H properly inserted in it. This tube or casing G has aseries of notches, 0 0, formed in it, upon one of its sides, at equaldistances apart, and extending in the direction of its length, asplainly shown in Figs. 1 and 3, with which notches a pinion or spurwheel, I, engages, secured to a horizontal shaft, J, turning in suitablebearin gs of the top or cap B of the lamp, this shaft having a milledhead upon one of its ends for convenience of turning it.

Kis abent'spring, secured at one end to the outside of the lamp-wicktube F, with its other end bearing against the opposite side of thewick-holder G to that with which the pinion I engages, as beforeexplained, the objectof which spring is to hold or bind the saidwick-holder G with a sufficient lateral force against the said pinion asto prevent the holdler from fallin g by its own weight through thewick-tube- F, no matter at what height its upper end, L, may be from theupper end of the wick-tube F.

The wick-l1older G it is intended should be made of such a length thatits upper end, L, without its becoming disengaged from the pinion I andthe wick-tube E, can be brought, by turning the pinion I in the properdirection therefor, above the upper end of the lampchimney M, inposition forits wick to belighted, when, turning the pinion in theopposite direction, it can be then drawn down through the length of thechimney to the position desired, and its flame regulated, as withkerosene-ramps of the ordinary construction, the wick, in this instance,remaining stationary in its holder, while it is moved up or down, as maybe necessary.

I claim as new and desire to secure by Let chamber of a coal-oil orother lamp as herein ters Pate11t described and shown in the drawings,for the -1.
